Rotating Magnetic Field's and Inductors.

[poynt99]

After that very helpful posting if I see one more jackass try to tell me what a horrible person I am, then they can shut their mouths and kiss my ass.

Thanks for your post and effort MH. I know all too well that most either can't or choose not to appreciate the effort that goes into posts which aim to explain and educate.

What this forum needs is more civilized posts and discussions, rather than the tirades this thread is being flooded with lately.

Again, the only core material I have ever seen increase Inductance by a magnet (without need of movement) is Finemet.
I suggest you get some toroids and test it out like I did in my demo video.

You can buy them here: http://www.elnamagnetics.com/catalogs 
If you have some kind of business you may be able to request a free sample.

I've attached some PDF's

It is interesting that in the Finemet document all the "Inductance vs. DC Bias Current" graphs show the inductance deceasing as the DC bias is increased. That seems contrary to your results Luc.

Which core model did you demo in your video?

Unfortunately I didn't bring the Finemet toroid with me and won't be going back to Ottawa until mid April.

I remember getting the part number from the Orbo topic in 2010 or 2011. I don't know if you can do a key word "Finemet" search in a specific topic?

Let me know if you do find the part number and I'll order a new one to test as well.

Thanks

My search for your posts did not pull up any part numbers. Suppose we need to find the orbo topics.

A Google search of "orbo" and "core" was not fruitful for me either.

Luc,

Did you perhaps use the same part number/core mentioned in this video that you linked to in a post you made discussing this? (Part number MP1305LF3T)
